how to retrive data from db to the table using getAll() - codeigniter

Question

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Unit extends CI_Controller {
/*Load supplier default*/
public function index($id='')
{
$this->load->model('Unit_model');
($id!='') ? $data["unit_details"]=$this->Unit_model->get_unit($id) :'';
$this->load->view('includes/header');
$this->load->view('includes/left_menu');
$this->load->view('unit/unit_manage', ($id!='') ? $data : '');
$this->load->view('includes/footer');
/*Submit supplier on add/edit */
}
public function post_unit()
{
$this->load->model('Unit_model');
$this->db->trans_begin();
// transaction begin statement
try{ //Use try catch statement here
$this ->db-> trans_complete();
if ($this->input->is_ajax_request()){
$case = $this->input->post('case');
//for both case use insert_customer function
if($case=='edit')
$insert_unit=$this->Unit_model->update_unit();
else
$insert_unit=$this->Unit_model->insert_unit();
$data['insert_unit']=$insert_unit;
//place commit statement
$this ->db-> trans_commit();
}
else
{
// through new exception statement
}
}
catch(Exception $e){ //statement here
// Place roll back statement
$this->db-> trans_rollback();
}
$this->sendData($data);
}
} ?>
This is my controller part.
class Unit_model extends CI_Model
{
protected $strTableName = 'suc_unit';
function __construct()
{
parent::__construct();
$CI = &get_instance();
$this->db->from($this->strTableName);
}
/*Load all details of table*/
function get_all()
{
$query = $this->db->get($this->strTableName);
return $query->result();
}
}
The above is my model... i want disply data in my page using the getAll() declared in the model. The insertion, updation and view should take place in the same page
<table id="tblListOfUnits" class="table table-bordered table-striped">
<tr>
<th style="width: 10px">Sl No</th>
<th>Unit Name</th>
<th>Unit Symbol</th>
<th style="width: 40px">No.Of Decimal</th>
</tr>
<?php
if(isset($units)){
$count = 1;
foreach ($units as $key => $unit) {
?>
<tr id="tr_<?php echo $unit->pk_int_unit_id; ?>">
